Abstract
Description
Die Erfindung betrifft eine Luftfederanlage für Nutzfahrzeuge, die im übrigen eine druckluftbetriebene Bremsanlage mit Betriebsbremse und Feststellbremse aufweisen.The invention relates to an air suspension system for commercial vehicles, which also have a compressed air-operated brake system with a service brake and a parking brake.
Luftfederanlagen für Nutzfahrzeuge sind beispielsweise aus
Nutzfahrzeuge mit Luftfederung an der Hinterachse oder auch an der Vorderachse sind in verschiedenen Ausführungsformen bekannt. Üblicherweise verfügen die Luftfederanlagen von Nutzfahrzeugen über eine eigene Luftversorgung. Zu diesem Zweck werden im Fahrgestell Luftbehälter unterschiedlicher Größe untergebracht. Neben diesen Luftbehältern für die Luftfederung sind weitere Luftbehälter für die Versorgung der Bremskreise, zumeist der Betriebsbremse und der Feststellbremse, erforderlich. Außerdem gibt es vielfach Nebenverbraucher, z. B. eine Luftfederung der Fahrerkabine, die mit Druckluft versorgt werden müssen. Der Luftvorrat der Feststellbremse wird vielfach für die Versorgung eines Anhängers herangezogen.Commercial vehicles with air suspension on the rear axle or on the front axle are known in various embodiments. The air suspension systems of commercial vehicles usually have their own air supply. For this purpose, air tanks of different sizes are housed in the chassis. In addition to these air tanks for the air suspension, additional air tanks are required to supply the brake circuits, mostly the service brake and the parking brake. There are also many secondary consumers such. B. an air suspension of the driver's cab, which must be supplied with compressed air. The air supply of the parking brake is often used to supply a trailer.
Bei Nutzfahrzeugen ist aus den genannten Gründen häufig eine große Anzahl von Luftbehältern vorhanden, deren Einbaukosten einkalkuliert werden müssen und deren zusätzliches Gewicht das Gewicht des Fahrzeugs insgesamt erhöht.For the reasons mentioned, commercial vehicles often have a large number of air tanks, the installation costs of which must be taken into account and the additional weight of which increases the weight of the vehicle as a whole.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Luftfederanlage für Nutzfahrzeuge derart auszugestalten, dass nur möglichst wenige Luftbehälter benötigt werden.The invention is therefore based on the object of designing an air suspension system for commercial vehicles in such a way that only as few air tanks as possible are required.
Zur Lösung dieser Aufgabe ist die erfindungsgemäße Luftfederanlage gekennzeichnet durch die Merkmale des Anspruchs 1.To achieve this object, the air suspension system according to the invention is characterized by the features of claim 1.
Die Luftfederanlage wird damit ausschließlich aus den Luftbehältern der Bremsanlage versorgt, und ein gesonderter Luftbehälter für die Luftfederanlage oder sogar ein gesondertes Luftversorgungssystem sind nicht erforderlich.The air suspension system is thus supplied exclusively from the air tanks of the brake system, and a separate air tank for the air suspension system or even a separate air supply system are not required.
Sofern es sich um ein Fahrzeug handelt, das für die Aufnahme von Sattelaufliegern oder Wechselbrücken vorgesehen ist und bei dem eine Veränderung der Rahmenhöhe des Zugfahrzeugs beim Ankoppeln und Abkoppeln eines Sattelaufliegers erforderlich ist, kann die Luftversorgung der Luftfederanlage ebenfalls von den Luftbehältern der Bremsanlage aus erfolgen. Der Luftverbrauch beim Anheben des Fahrzeugrahmens ist verhältnismäßig gering, so dass das Anheben des Fahrzeugrahmens ohne wesentliche Verzögerung erfolgen kann.If it is a vehicle that is intended to accommodate semi-trailers or swap bodies and which requires a change in the frame height of the towing vehicle when coupling and uncoupling a semi-trailer, the air supply to the air suspension system can also be provided from the air reservoirs of the brake system. The air consumption when the vehicle frame is raised is relatively low, so that the vehicle frame can be raised without any significant delay.
Der fehlende Behälter der Luftfederanlage kann dadurch ausgeglichen werden, dass das Luftversorgungssystem der Bremsanlage mit höherem Energievorrat betrieben wird. Dies kann erreicht werden durch Integration des Luftvolumens der Feststellbremse in die Kreise der Betriebsbremse. Dadurch erhöht sich das gesamte Luftvolumen der Bremsanlage, und es wird insgesamt mehr Energie in den Behältern gespeichert als bei Anlagen mit separaten Luftbehältern in der Feststellbremsanlage.The missing container in the air suspension system can be compensated for by operating the air supply system of the brake system with a higher energy supply. This can be achieved by integrating the air volume of the parking brake into the circuits of the service brake. This increases the total volume of air in the brake system, and overall more energy is stored in the tanks than in systems with separate air tanks in the parking brake system.
Es liegt auf der Hand, dass eine Reduzierung der Anzahl der benötigten Luftbehälter, die durch das erfindungsgemäße System erreicht wird, Gewichts- und Kostenvorteile zur Folge hat. Andersherum kann die mögliche Nutzlast des Nutzfahrzeugs erhöht werden, und das geringere Leergewicht des Fahrzeugs reduziert den Kraftstoffverbrauch.It is obvious that a reduction in the number of air tanks required, which is achieved by the system according to the invention, results in weight and cost advantages. Conversely, the possible payload of the commercial vehicle can be increased, and the lower curb weight of the vehicle reduces fuel consumption.
Vorzugsweise wird das Luftsystem der Feststellbremse in das Luftsystem der Betriebsbremse integriert. Wie bereits hervorgehoben, erhöht dies die potenziell durch das Luftversorgungssystem speicherbare Energie. Diese Energieerhöhung kann dadurch erreicht werden, dass das üblicherweise auf niedrigem Druckniveau betriebene Luftsystem der Feststellbremse in die Kreise der Betriebsbremse integriert wird.The air system of the parking brake is preferably integrated into the air system of the service brake. As already pointed out, this increases the energy that can potentially be stored by the air supply system. This increase in energy can be achieved by integrating the air system of the parking brake, which is usually operated at a low pressure level, into the circuits of the service brake.
Die Integration des Kreises der Feststellbremse in das System der Betriebsbremse ist an sich nicht neu. Die Möglichkeit, auf einen gesonderten Luftdruckbehälter für die Feststellbremse zu verzichten, ist bereits genutzt worden. Es ist bisher jedoch nicht gesehen worden, dass auch ein gesonderter Luftbehälter für die Luftfederung entbehrlich ist, wenn, wie erwähnt, mit erhöhter Energiereserve gearbeitet wird.The integration of the parking brake circuit into the service brake system is not in itself new. The possibility of doing without a separate air pressure tank for the parking brake has already been used. So far, however, it has not been seen that a separate air tank for the air suspension is also unnecessary if, as mentioned, an increased energy reserve is used.
Die Erfindung ermöglicht also eine erhebliche Gewichts- und Kosteneinsparung.The invention thus enables considerable weight and cost savings.
Im folgenden werden bevorzugte Ausführungsbeispiele der Erfindung anhand der beigefügten Zeichnung näher erläutert.In the following, preferred exemplary embodiments of the invention are explained in more detail with reference to the accompanying drawings.
Die einzige Figur zeigt schematisch ein erfindungsgemäßes Luftversorgungssystem für die Bremsanlage und die Luftfilteranlage.The single figure shows schematically an air supply system according to the invention for the brake system and the air filter system.
